pE'mcnAfitia-Rm CLAMP.

T 0 all whom it moi concern:

Be it known that I,- DoNAnn E. Aoxsw, a

citizen-of the United States, residing in the city' of Portland, county of- Multnomah, and State of Oregon, have invented certain new and useful Im 'rovements in Detachable-Rim Clamps, of ',w 'ich the'following a specification. i

My invention relates to detachable rim 1o clamps. such as are used forsecuring a detachable rim in place upona'ivhel and at the sametime wedging between the wheel felly, or telly band, and a detachable rim, forthe purpose of preventing any looseness therein.

The'principal object ofmy invention is to provide such a clamping, or fastening, device which is capable of certain expansion, or contraction, in order that it may-be more 2 0 readily fitted to the space between the de tacha'ble rim and the felly band,

In order that others may clearly understand my invention, I have illustrated the preferred form thereof in the accompanying sheet of drawings, which I will now describe.

the-body having a bolt hole3 therethrough, v by means of which it is secured in place as hereinafter referred to, and the head,-or hilllike, portion 2 is provided in its top surface 40 with a series of teeth, or notches, as 4, extending across the same in a directiou'parallel with the plane of the body gl, and also provided with a transversely, extending groove 5, clearly shown in top plan view, Fig. 3. The top, or upper portion, 6, of my clamp, is provided with corresponding notches, or teeth, on its under side, as clearly indicated, adapted to fit into the notches 4, in the top surface-of the main' portion of the device. Said top is also provided with a transversely extending rib '7, adapted to fit into groove 5, in the manner clearly indicated in Fig. 1. The object of this interfit I between the groove 5 and the rib 7, is to prevent the top from any relative movement Specification of Letters Patent.

laterally-of said device which would be 1011- gitudinallyof the teeth, or notches, 4. The teeth, or notches, 4, prevent any movement relatively in' the opposite direction of said top member. The head and bill-like portion 2, of the main member 1, is wedge form, asis also the top, whereupon if the top member be adjusted inwardly, as indicated in dotted lines, Fig. 2, the thickness of the wedging portion which fits between the detachable rim 8, and the felly band 9. is increased, and i if said top member 6, is adjusted in the o posite direction one notch, or more, t 1e" thickness of the wedging portion of the device is reduced.

The device is put into place, as indicated in Fig. 4, the bolt 10 of the telly passing through the hole 3, in the body member 1. As a rule, these clamp devices are spaced apart around the outside of the wheel rim in suflicient number to securely hold a detachable rim in place. 7

Thus it will be seen that I have provided a' combination clamp and wedging device which is capable of certain adjustments, whereby to make possible a better fit of the device between the detachable rim 8, and the felly band 9. It is also possible many times to us" my improved adjustable clamping den where a similar device made in one piece would be too large, or too small to serve the purpose for which it is intended.

I am aware that changes can be made in the form of my device without departing from the spirit thereof. and I do not. therefore, limit the invention to the particular form here shown, except as I may be limited the hcrctoappcndcd claims.

I claim:

1. A clamping device of the character shown and described, comprising a. body portion provided with a wedgingportion adapted to be inserted underneath a detachable wheel rim. and a top portion adjustable thereon, whereby to increase or diminish the thickness of the portion inserted under said wheel rim.

2. A clamping device of the character referred to adapted for use with a detachable wheel rim, which clamping device has a two-part wedging portion, the parts of which are adjustable relative to each other, whereby to change the thickness of the wedging portion of said device, and means for securing said device in place.

3. In combination with a wheel rim and a detachable rim, a clamping device havin a two-part wedging portionjadapted to be inserted therebetween, the parts'of which are adjustable relative to each other, whereby to increase, or diminish, the thickness thereof, and means for securing said clamping device in place. 1

4. A demountable rim clamp of the character shown and described, comprising a body having a head of tapering form and provided in its upper face with notches, a top member of tapering form provided in its underside withnotches adapted to mesh with-the notches in said head, whereby as .said top portion is adjusted in opposite directions relative to said-head, the thickness ofQthe wedging portion of said clamp is increased, or diminished, substantially'as and for the purpose described.

, 5. In combination with a wheel rim and a demountable rim adapted therefor, a clamping-device having a body with means for securing it to said wheel rim and having a head of tapering form adapted to be inserted between said wheel-trim and said de tachable rim, 5 top member adjustably mounted upon said head and having interfitting connections therewith to prevent movement relative thereto, said top member being adapted to increase or diminish the thickness of the'portion' of said head between said wheel rim and said detachable rim as it-is adjusted in one direction or the other relative to said head, substantially as described.

6. In combination with a wheel rim and a detachable-rim therefor, a clamping device comprising a body having means for securing 1t to the side of said wheel rim, and having a head of tapering form provided. in its upper surface with notches, a top, or cap, member having in its under side corresponding notches adapted to mesh with the notches in said head, whereby to be adjusted to different positions thereon to increase or diminish the thickness of said head, one of said parts being provided with a transversely extending groove and the other being provided with a transversely extending rib adapted to fit into said groove,

whereby to prevent sliding movement of one part relative to the other, substantially as and for the purpose described. Signed at Portland, Multnomahcounty, Oregon, this 7th day of January, 1916.
